[osg-users] Adding OGRFeatures to the global Index

[Auke-Dirk Pietersma]

Hi,

I'm having a hardtime finding documentation on populating the global index with ogrfeature data, such that i can use the IntersectionPicker. Can anyone point me in the right direction?

    
Code:

auto map = mapnode->getMap();
OGRFeatureOptions feature_opt;
feature_opt.name() = url;
feature_opt.url() = url;
feature_opt.buildSpatialIndex() = true;

FeatureGeomModelOptions fgm_opt;
fgm_opt.featureOptions() = feature_opt;
fgm_opt.styles() = new StyleSheet();

map->addModelLayer( new ModelLayer(url, fgm_opt) );




Now i would like to pick the geometries within the scene. I do ofcourse get to see the geometries with correct style. However the picking provides an empty result.

... 

Thank you!

Cheers,
Auke-Dirk
